Catted Vs. ORY I already have a magnaflow catback system and was lookin to put on some decent headers. What kind of performance gains can be expected with a catted setup as opposed to an ORY setup?

The cats will only cost you 3-5 HP ish, so there really isn't that much of a performance gain by running W/O cats. Cats will also make your car legal and will help reduce the annoying sound of the LS1 rasp and stong exhaust fumes.

Go with a catted ypipe, it sounds and smells better. Performance loss is negligable.
The ONLY real benefits of a catted Y pipe are 1. keeps you somewhat legal (even though ALL LT's are illegal) 2. Helps cut rasp
Benefits of a ORY
1. Better ground clearance unless you get a catted Y pipe fabed at a shop
2. Cheaper
3. I like the raw sound of a V8 withOUT cats

Yea, it seems that the technology has caught up, when I do my headers im doing Dynatech Super MAXX with their catted y, they also include the straight pipes if need be it

since you dont have loudmouth, id run an ory. **** even if you did have LM id get the ory. either way with LT's and catted y, you gained a helluva lot more then you lost. good luck.

See what people are forgetting though is that QTP's dont offer a stainless Y-pipe, its aluminized. Kooks however does offer a stainless y-pipe. I belive Kooks, Dynatech, and Stainless works are the only companies whose whole setup is SS, correct me if Im wrong.. I was going to go the QTP route myself but am tempted to do the kooks now b/c their whole system is SS and it'd match my SS borla...... who knows what I'll end up getting. Either way, all the systems are good, its just a matter of what you want, what you can afford, and which system fits your needs.
